OK, I have to clarify my response, as I replied from work where the firewall wouldn't let me see your schematic.
That schematic is referring to Chinese 6N2 and 6N4 tubes, not Russian 6N2P and 6N4P tubes. As for whether the Chinese 6N4 really is a 6N2 or even 6N2P substitute, I can't find a datasheet.
